Question

我正在尝试将图片上传到服务器，但我遇到了问题。这是我的代码：

UIImage *image = [UIImage imageNamed:@"profileImage.png"];

NSData *imageData = UIImagePNGRepresentation(image);

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:@"http://myserver.com/upload_img.php?&user_id=6&image=image.png" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData){
    [formData appendPartWithFileData:imageData name:@"image" fileName:@"image.png" mimeType:@"image/png"];
}

    success:^(AFHTTPRequestOperation *operation, id responseObject){
    NSLog(@"Success: %@", responseObject);
}

      failure:^(AFHTTPRequestOperation *operation, NSError *error){
    NSLog(@"Error: %@", error);
}];

我从NSLog获得“Success：{error =”“;}”，但服务器没有更新。我做错了什么？

修改

好的，图片正确上传，但我们不得不在服务器上使用GET而不是POST来检索图片。为什么会这样？

试试这个

UIImage *image = [UIImage imageNamed:@"profileImage.png"];
        NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
        AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager POST:@"http://myserver.com/upload_img.php?&user_id=6&image=image.png" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData){

    }
     {
          [formData appendPartWithFileData:imageData name:@"image" fileName:@"image.png" mimeType:@"image/png"];
        } success:^(AFHTTPRequestOperation *operation, id responseObject) {
            NSLog(@"Success: %@", responseObject);
        } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
            NSLog(@"Error: %@", error);
        }];

固定！通过POST调用，我需要设置正确的参数：@{user_id:@6}。现在工作得很好！
